Cucumeris is an older biological control, but still one of the best. On a cost basis, there is no other thrips predator that even comes close. You can apply cucumeris on foliage to eat young larvae that are on the leaves.
You can apply Hypoaspis (Stratiolaelaps) to the soil to help by consuming thrips pupae (and fungus gnat eggs and larvae) in the soil. Stratiolaelaps is a generalist soil predatory mite that is also capable of controlling fungus gnats, springtails, root weevils, etc.
